ABSTRACT
This is like a standard solution that is used in a chemical analysis. It is a solution in which the concentration is precisely known. One can determine the concentration of a standard solution for a titration analysis by the process of standardization. To do this, a primary standard is used to accurately determine the molarity of the standard solution. The primary standard solution is prepared by first oven drying the primary standard to a constant mass, and then dissolving a known amount of it in a known volume of liquid. A primary standard must be very pure, reasonably soluble, stable, nonhygroscopic, and of fairly high molar mass.
